T0 at whom it may concern: 7

Be it known that I, WILLIAM LOUDEN, a resident of Fairfield, in thecounty of Jefferson and State of Iowa, have invented certain new anduseful Improvements in Hay-Elevators; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to hay carriers in which a brake, or otherlockingdevice is used to catch and hold the hoisting rope, and thus sustain theload while the carrier is traversing the track; and it consists first,of a tilt ing frame or housing adapted to receive the hoisting rope andpermit its passage there'- through, said tilting frame being pivoted inthe fraine of the carrier and connected to the brake which is alsomounted in the carrier frame so that the passage of the hoisting ropethrough the tilting frame in one direction will automatically releasethe brake from the rope and its passage through said frame in theopposite direction will automatically bring the brake in engagement'withthe rope.

It further consists of a set of compressing pulley blocks hung in theloop of the hoisting rope which is formed by its passage through thecarrier, one end of the hoisting rope being passed over a sheave in thecarrier frame stop to placev upon the hoisting rope.

and brought down from the carrier and connected to one of the pulleyblocks, and a stop placed upon said end of the rope between the carrierand the pulley block to which it is connected, so as to prevent thepulley blocks with their load from being drawn against the frame of thecarrier or be arrested with a jar by the stop on the rope and to releasethe carrier from a stop on the track.

It further consists of combinations and arrangements of parts set forthin the following specification and pointed out in the claims.

In the accompanying drawings Figure l is a side elevation of a carrierembodying my invention, the front side of the carrier frame beingremoved. Fig. 2 is a similar view showing the brake engaging the rope.Fig. 3 is a sectional view on the line m-y of Fig. 2. Fig. 4. is avertical section of an improved form of Fig. 5 is a sectional view ofthis stop on the line and also a modification of the brake and its Iconnection Withthe tilting frame. Fig. 7 is a further modificationshowing the application of the compressing pulleys and the rope stop toa common carrier.

A represents the frame of a hay carrier having wheels A, adapted to runon a track B to which a stop 0 is secured. Mounted in one end of thecarrier A is a sheave D, and pivotally supported at A in the other endof the carrier, is a frame or housing E. In the lower end of saidpivoted frame is a sheave D and in its upper end is an auxiliary sheaveD A brake shoe or clutch F is pivoted in the carrier frame, and its freeend is pivotally connected to the frame E by means of a link F. Saidbrake shoe is preferably made with prongs b to straddle the sheave D andbe pivoted to the same axle on which the sheave D turns.

A hoisting rope G is passed first over the auxiliary sheave D then overthe other sheave D, then down and through the compressing pulley blocksH and H, then up and over the sheave D in the other end of the carrier,and then down to the frame of the pul-' ley H, where its end isattached. The load to be elevated will be attached to the hooks of thecompressing pulleys H and H in the ordinary way, and the power toelevate it will be applied to the free end of the rope.

It will be seen that when the load is being elevated the draft of therope in the direction of the arrow will tilt the lower end of the frameE upward, or in the same direction the rope is moving, and this willlift the brake off the rope, as shown in Fig. 1, and letit pass freelyover the sheaves. Should the horse slacken the rope, or should the ropebecome slackened by being detached from the horse, or otherwise, theinstant it commences to run back it will draw the pivoted frame E backwith it, and this will bring the brake down against the rope, as shownin Fig. 2, and will hold it from running back and this'will keep theload from falling from the carrier. It will also be seen that this brakearrangement is entirely automatic, holding the brake off the rope whilethe rope is moving in the di- IOO rection of the arrow and letting therope pass freely in this direction, but when the direction of the rope Gis reversed, the brake will be brought against the rope and stop itsmovement, in that direction. Should the singletree break when the loadis elevated nearly to the carrier, this device will instantly andautomatically check the descent of the load, and thereby preventaccidents by the falling of the elevated load.

To hold the carrier A stationary on the track 13 a latch lever J ispivoted to the carrier frame and its inner end is adapted to engage thestop C. To the outer end of the latch lever J a depending yoke K ispivotally connected-the rear half of which only is shown in Figs. 1 and2. The lower end of said yoke is provided with a loop K, which standssubstantially at right angles to the upper part, and through this loopthe end of thehoisting rope leading down to the pulley block II ispassed.

A portion of each side of the carrier frame is extended backhorizontally from the axle on which the sheave D turns, and is rivetedtogether at a as plainly shown in Fig. 3. This forms a guard to preventthe end of the rope which is secured to the pulley block H from runningoff the sheave D. The yoke is wide enough to straddle this portion ofthe carrier frame and therefore the vertical movement of the yoke willnot be interfered with by it.

Upon the end of the rope extending from the carrier down to the pulley Ha stop I is placed, the oflice of which is to prevent the pulleys H andH from being drawn against the frame of the carrier or in contact withthe sheaves D or D thus preventing injury to any of the parts; also, toengage the loop of the yoke K and release the latch J from the stop 0,and let the carrier traverse the track B. This stop I is preferably madeadjustable so it may be readily slipped up or down the rope so as toregulate the height to which the pulley H or H will be drawn.

It will be observed that by the location of the stop on the end of therope between the pulley block and the carrier the compressing pulleysand the load they are carrying will not he suddenly arrested by the stopcoming in contact with the carrier, or the trip mechanism with which thecarrier is provided, but the vertical ascent will be eased off andconverted into the horizontal movement along the track by the release ofthe carrier from the stop on the track so as to avoid the upsetting orscattering of the load in changing from the vertical to the horizontalmovement.

Any suitable form of stop may be used, but my preferred form comprises aplate or disk 1 having a central opening 2 for the passage of the rope,and an arm 3 projecting at right angles from said disk. The arm 3 ismade with two perforations 4, 4, with a web between them, and from theweb prongs 5, 5, project, to produce aV-shaped recess 6. The rope Gafter passing through the perforations or openings 2 in the disk 1ispassed through the upper perforation 4 in the arm 3, then between theprongs 5,5, and finally through the lower perforation 4. of the arm 8.To adjust this stop along the rope all that is necessary is to slackenthe rope so as to form a loop and draw it out of the V-shaped recess 6.It can then be readily slipped up or down the rope, and when the loop ofthe rope is drawn into the recess again, the stop will be securely heldat any desired point on the rope.

The carrier being held stationary on the track by the inner end of thelatch J impinging against the stop 0, and power being ap plied to thefree end of the rope G, the load which may be connected to the pulleys Hand H while they are spread apart, will be compressed by the action ofthe rope on the pulleys and then elevated until the stop I strikes theloop K of the yoke K, and releases the latch J from the stop 0. Thecarrier being released from the stop will be free to run along thetrack, and the weight of the load will draw the tilting frame E backsuiiiciently to bring the brake shoe F against the rope, which will holdthe load suspended. The load being dis charged and the carrier returned,the end of the latch will catch behind the stop, as before. The carrierbeing moved still farther back on the track, the upper end of thetilting frame E will come in contact with the stop O,wl1ich will tilt upthe frame and release the brake from the rope, and permit the pulleyblocks to descend for another load. There should be suflicient roombetween the latch J and the end E to permit the frame E to tilt downwardfreely and make the brake catch the rope at any point in the elevationshould it be necessary.

It is preferable to have two sheaves in the tilting frame E, but it maybe operated with one alone by placing it more nearly in the middle ofthe frame and adjusting the pivot A to correspond. The brake shoe mayalso be mounted in any suitable way in the frame of the carrier so as togive it a movement to and from the rope which can be operated by thetilting motion of the frame E.

In the form of invention shown in Fig. (i, the carrier is substantiallythe same as that in Figs. 1 and 2 except in the arrangement of thepulleys, the track stop and the latching device. The brake shoe F isalso somewhat modified by making slots 6 in the prongs b which willslide on the axle of the sheave or pulley D, by which means the link Fused to connect the brake shoe to the pivoted frame E may be dispensedwith,and the necessary longitudinal movement of the brake shoe beprovided by slots e. A latch G is hinged to the plate 0 which is boltedto the track B, and is arranged to impinge against a bolt 1) in theframe of the carrier. The plate 0 has a depending loop 0 which catches afinger C on the latch C to prevent it from dropping down. A spring S mayalso be used to hold the latch in engagement with the bolt 1).

' The carrier is released from the track by a stop 1 coming in contactwith a trip bolt 70' which hasavertical sliding movementin the frame ofthe carrier, and which lifts the free end of the catch and permits thebolt 1) to pass under it and let the carrier move along the track.

The rope G after passing over the pulleys D and Din Fig. 6 is passedthrough the pulley blocks H and H and then up around the pulley D fromthe outside and down on the inside to the pulley block H where it issecured. The trip stop I is secured to the end of the rope between thepulley D and pulley. block H and is adapted to come into contact withand lift the trip bolt K, as well as to prevent the pulley blocks H andH from being drawn down against the carrier and injuring them on thecarrier.

In the application of the part of the in vention shown in Fig. '7 twosheaves L L are mounted in rigid hearings in the carrier L A lever L ispivoted at a point between its ends in the carrier frame and at one endprojects beyond the end of said frame, where it is provided with a hookL adapted to engage a suitable stop on the track. The inner end of thelever I. is provided with a brake shoe L adapted to engage the rope Gpassing over the pulley L. An arm or yoke L is attached at one end tothe lever L its other end being in proper position to permit the passagethrough it of the rope G. The rope G, after passing over the sheave L,passes under the pulley blocks H and H then over the sheave L, and itsend is then'attached to the frame of the pulley block H The stop I isattached to the rope G, in this form of the invention, the same as abovedescribed in connection with the preferred form of the invention.

The devices constructed and arranged as above set forth for elevatinghay by a suitable sling or forks, and holding .it at any desiredelevation in a compressed condition are applicable to almost any kind ofhay elevator wherein the hay is elevated perpendicularly to a determinedheight and then drawn in a horizontal direction by the same power thatelevates the load.
